The invention relates to an obstacle removal and weeding robot for an electric equipment fence. The obstacle removal and weeding robot comprises a trolley, wherein a controller, a water tank and a water pump are arranged on the trolley; a remote receiving module is arranged on the controller; a weeding spraying agent is arranged in the water tank; a fixing seat is arranged at the front end of the trolley; a second motor is arranged at the fixing seat; a fixing plate is arranged at an output shaft of the second motor; two engaged gears are arranged on the fixing plate; first connecting plates are respectively arranged on the gears; each first connecting plate is hinged to one end of a mechanical arm; a clamping sheet is arranged at the other end of each mechanical arm; a second connecting plate is hinged to the middle part of each mechanical arm. The obstacle removal and weeding robot has the advantages that by utilizing remote controlling, the trolley is moved within the range of the electric equipment fence; by controlling the mechanical arms to do reciprocating movement, the function of removing foreign matters is realized; by controlling the water pump, the weeding spraying agent in the water tank is sprayed out through a spray nozzle, so the weeds in the electric equipment fence can be removed, and the short-circuiting of high-voltage equipment to ground is avoided.
